9x and 5x are "like terms."
9x - 5x produces the same result as does -5x + 9x.
See the attached picture to better understand the problem
we know that
in the right triangle ABC
sin 63°=AB/BC
AB is the opposite side angle 63-----> x cm
BC is the hypotenuse-----> 85 cm
AB=BC*sin 63°-----> AB=85*sin 63-----> AB=75.736 cm
AB=75.8 cm
the answer isthe value of x is 75.8 cm
Answer:
7.5 Hours (This is questioned weird though so it could be different)
Step-by-step explanation:
Just add 9 to 6 and you'll have 15 divided by two equals 7.5.
Or since it takes 6 hours for both, multiply by 2 equals 12
The product asked above may be given expressed by the expression,
(2) x (sqrt 3) times (sqrt 12)
Two is also equivalent to sqrt of 4. The operation may be expressed as,
(sqrt 4) x (sqrt 3) x sqrt (12)
The product is sqrt (144). This gives an answer of 12 and it is rational.
